3. Suction & Drainage Parameters
-
Permissible Suction Pressure: -16.7 ~ +50 kPa
-
Drainage Pressure Requirement: Normal pressure ≤ 0.1 MPa; Surge pressure ≤ 0.5 MPa
-
Recommended Suction Pipe Inner Diameter: ≥ 16 mm (3/4 inch)
4. Control & Adjustment
-
Control Type: Pressure compensator controlsuperscript:4]
-
Pressure Adjustment: Turning the pressure adjustment screw clockwise increases the pressure; each full turn adjusts the pressure by 6.5 MPa (for A37 series with code “C”)
-
Flow Adjustment: Turning the flow adjustment screw clockwise decreases the delivery flow; the minimum adjustable flow is 10 cm³/rev, and each full turn of the adjustment screw changes the flow by 2.9 cm³/rev.
5. Installation Notes
-
Use a flexible coupling to avoid bending or thrust stress on the shaft; maximum permissible misalignment ≤ 0.1 mm TIR, maximum permissible misangular ≤ 0.2°.
-
The length of the drain pipe should be less than 1 m, and the pipe end should be submerged in oil.
-
When using steel pipes for suction or discharge ports, avoid excessive load from the piping to prevent excessive noise.
-
The pump is preset to maximum delivery and minimum discharge pressure at the time of shipment; adjust according to system requirements.
